Native to Europe, Yellow toadflax and Dalmatian toadflax can typically be found on roadsides, grasslands and in crop fields. Like many other weeds, toadflaxes have been introduced to North America as decorative plants but they are now having adverse effects. Whilst these weeds may look pretty and provide decorative appeal, they soon escape cultivation and can cause some serious problems. As part of a new CABI Podcast series, CABI experts Dr Hariet Hinz and Dr Ivan Toševski were interviewed from CABI in Switzerland, who explained to us what measures they are taking to control the spread of toadflax.

Are you a crabber, waterman, or concerned citizen? We need your help to detect and assess the status of Chinese Mitten Crabs. The "Mitten Crab Watch" website provides information on the invasion of the mitten crab and allows users to more easily report catches.

Please help us detect live mitten crabs by reporting any sighting in North America. We are especially interested in collecting sightings from the Chesapeake Bay, Delaware Bay, Hudson River, and San Francisco Bay --- where the crab has been common in the past. Please visit the Mitten Crab Watch website to learn more about the crab and to report sightings.

The Angler AIS Prevention Pass (AISPP) is required for all individuals who fish in Montana. This program was initiated by the 2017 Montana Legislature to help fund the fight against aquatic invasive species in Montana. Non-resident watercraft launching in Montana must purchase a Vessel AIS Prevention Pass (AISPP). Purchase the Vessel AISPP at FWP regional offices or through the Online Licenses Service.

The Montana Department of Agriculture (MDA) has issued an emergency quarantine order to protect against the introduction and spread of the emerald ash borer (EAB), a destructive wood-boring beetle that has already killed millions of ash trees in North America. The order was motivated by the removal of federal domestic quarantine regulations by the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS). "It is important that we remain vigilant and do everything in our power to make sure that the emerald ash borer doesn’t find a way into Montana," said MDA Director Mike Foster. "This quarantine order protects the green ash woodland resources in eastern Montana that provide habitat for many wildlife species as well as economic benefits to livestock producers and rural communities."

Montana’s emergency quarantine order restricts EAB from entering the state in any form, as well as the movement of live ash trees, parts of ash trees capable of harboring live EAB, and any other articles determined potentially hazardous. MDA will accept public comment regarding the quarantine order until February 26, 2021.

Working to reduce health and environmental risks from pest management, as well as improve practices, and increase Integrated Pest Management (IPM) adoption. Our focus areas involve tactics and tools for plant protection, enhancing agricultural biosecurity, and IPM for sustainable communities.  The program encompasses four areas; agronomic crops, communities, pest diagnostic facilities, and pesticide education.  The overall goal of the Integrated Pest Management program is to develop and deliver information on IPM practices in Montana.

Reporting suspect and/or invasive species is very important! In Montana, where you report invasive species depends on what kind of plant or animal they are, so that the correct agency can respond to your report.

To prevent and stop invasive species we need your help. You can take simple actions to help prevent the introduction and spread of noxious weeds and invasive species.

Prepared by: Creative Resource Strategies, LLC. In 2015, the Council contracted with Creative Resource Strategies, LLC to conduct an assessment and gap analysis of Montana's invasive species programs. This report documents the outcomes of that assessment and analysis, and includes an articulation of key gaps as well as a set of recommendations to refine strategies and approaches, and enhance efficiencies, to address invasive species. It is important to recognize that the information from survey respondents represents a snapshot in time—the 2015 fiscal y ear—for each contributing entity. In addition, the information obtained from survey respondents was, in numerous cases, incomplete, and in some cases, not accurate. Nevertheless, the information obtained is of value to identify gaps and inform a set of recommendations.

The Montana and Washington invasive species councils have joined forces to stop wild pigs from crossing borders. The two councils issued a report with recommendations and best management practices aimed at helping federal, state, provincial and local landowners manage wild pigs in the western United States and Canada. "Wild pig populations are expanding in the western provinces of Canada and in the United States." said Stephanie Criswell, coordinator of the Montana Invasive Species Council. "We are at a unique point in time where we can work together to prevent Canadian wild pigs from spreading across borders into unaffected states like Montana."

In early 2020, the two invasive species councils convened a working group of more than 40 federal, state and Canadian feral swine experts to discuss challenges and opportunities to prevent feral swine along interstate and international borders. Finalized this month, the report includes 22 recommendations that address five strategic areas of feral swine management. Recommendations include standardizing communications to the public, expanding monitoring networks by partnering with non-traditional organizations such as hunting groups, and formalizing notification protocols for reports that will be shared between state and provincial authorities along the international border. The complete report can be found at misc.mt.gov.
